摘　　要：1 000 Nm参考式扭矩校准装置,以高精度扭矩传感器为主要部件,并辅以软件控制系统执行自动加载、保持及对中的功能。文章详细阐述了装置的工作原理、结构和关键技术。通过对相关技术数据的分析计算,结合中国计量科学研究院的检定报告,装置的扩展不确定度U可以达到3×10-3 Nm。The 1 000 Nm torque calibration device with referencetransducer is proposed in this article. The core component is the highaccurate torque sensor with control system for carrying out automaticloading, holding and automatic concentricity. The operation principle,structure and key technology of the device are introduced in detail. Byanalyzing and calculating the relevant technical data and the verificationreport issued by NIM （National Institute of Metrology）, the uncertainty Uwhich it can reach is 3×10^-3 Nm.
